Wickens, 29, was hospitalized after his car soared into the fence during the seventh lap of the 200-lap race. The race was delayed for two hours after the incident. Wickens needed multiple surgeries to treat his injuries, which reportedly included two broken legs and a broken right arm.

The Associated Press reported that surgeons stabilized Wickens' spine with titanium rods and screws. The extent of the damage to Wickens' spinal cord is unknown.

Support has poured in for Wickens since the wreck, including from teammate and fellow Canadian James Hinchcliffe.

"I was there for you then, I'm here for now, I'll be there for whatever you need to get back," Hinchcliffe wrote on social media. "Missing my little bro big time, but he’s in good hands. Sorry I've been MIA but thank you so much for all the messages & support for @robertwickens. Gotta bring him home some hardware!"

Wickens was in his first season as an IndyCar driver. He spent the 2017 season as a test driver before being bumped up to a full-time role. Through 14 races, Wickens appeared on the podium three times. He entered the Pocono race coming off his best result to date, a second-place finish at the Honda Indy 200 in July.
